Study Notes
Introduction to Physical and Chemical Properties of Matter
- Matter is anything that has mass and takes up space.
- All types of matter have unique properties.
- Properties of matter can be divided into two categories: physical properties and chemical properties.
- Physical properties can be observed or measured, such as length or mass.
- Physical properties do not change the chemical composition of a substance.
- Chemical properties refer to how a substance interacts with other substances during a chemical process or reaction.
- The combination of physical and chemical properties gives matter its identity.
- Matter can exist as a pure substance, such as an element or a compound.
- An example of a pure substance is hydrogen gas.
- An example of a compound is water, made of hydrogen and oxygen.
- Understanding the physical and chemical properties of matter is important in studying its behavior and reactions.
- These properties help scientists identify and classify different types of matter.
